Huddersfield lost 2-1 on the night to MK Dons but still reached the npower League One play-off final with a 3-2 win on aggregate.
The Terriers, leading 2-0 from the first leg, went ahead on the night through leading scorer Jordan Rhodes, only for Daniel Powell to level before half-time.
Although substitute Alan Smith scored with a header in injury-time, Huddersfield held on to make sure of their place at Wembley.
Dons manager Karl Robinson will again be haunted by a perceived "curse" of match officials after suffering more play-off heartbreak.
He thought his side should have been given a first-half penalty when referee Scott Mathieson missed an apparent push from Sean Morrison on Charlie MacDonald, which could have changed the course of the tie.
Robinson told Sky Sports of the incident involving Morrison and MacDonald: "It's a penalty. To be fair to the referee, if he has missed it, I'm sorry. But it is a blatant penalty.
"It just seems the curse of refereeing decisions in the play-offs.
"Last year, one went against us at Peterborough. Then there was the one the referee let in on Saturday, which cost us the goal.
"Again, today, we have been done by officials. You can keep blaming officials. But then the players have gone out and made a right, good go of it."
Huddersfield boss Simon Grayson has called on his side to now go out and win promotion when they face Sheffield United at Wembley.
"It is a great occasion but there is only one thing that matters when you get to Wembley and that is winning because you might as well finish 15th in the division and be on holiday two weeks ago.
"We know what we need to do."
